India's teenaged Grandmaster R Praggnanandhaa began his campaign in the star-studded Julius Baer Generation Cup online rapid tournament, the seventh leg of the USD 1.6 million Meltwater Champions Chess Tour, with wins over veteran Vasyl Ivanchuk and Jan Kryzstof Duda of Poland. He then beat another veteran Boris Gelfand in the third round before losing to American 15-year old Christopher Yoo on Monday. The 17-year old Chennnai prodigy came up trumps against 53-year old Ukrainian legend Ivanchuk in a battle of generations to pick up three points.
